Description
Technical field
The utility model relates to solid-liquid separating equipment, particularly bag type filtering machine.
Background technology
Bag type filtering machine is a kind of important solid-liquid separating equipment.Conventional bag type filtering machine mostly is stainless steel equipment, and structure chart is seen Fig. 1.Generally be made of cylindrical shell 2, gland 6, inner barrel is by the fixing filter basket 9 of annular brace mechanism 7, is lined with filter bag 8 in filter basket 9 inside during use.For to being incubated by the press filtration material, also be furnished with chuck 11 and chuck circulation fluid import 10 and outlet 3 on the filter of being everlasting, pass into the insulation liquid of circulation in chuck.Material inlet 4 and filtrate (liquid 1 are generally established in side and bottom at filter.During conventional design, compressed air generally enters from material inlet 4, mineralization pressure field above the material in the filter basket, the natural recess formation source of the gas center above material.Under the effect of the pressure differential that source of the gas center and side, bottom space form, reach the purpose of filtrated stock.
In filter process, compressed-air actuated stroke can with a in Fig. 1 or c and three dotted line signals of b, represent that respectively air is through shortest route and the longest stroke of material.Ideal situation is that shortest route a or c and the longest stroke b are almost equal, and each stroke material inside and outside pressure differential is close, the material of process almost complete simultaneously Separation of Solid and Liquid.But in the situation that in the filter basket, material is more, because a or the c stroke of compressed air process are the shortest, the top material is realized the Separation of Solid and Liquid of better effects the soonest.After this, the resistance of a or c stroke is much smaller than the b stroke, cause most compressed air directly to discharge from discharging opening along stroke a or c on material top, pass through b stroke (this phenomenon is called " short circuit ") no longer downwards, thereby make the bottom material can't realize good Separation of Solid and Liquid at all.In filter basket in the less situation of material, compressed air especially directly the filter opening on logical filter basket top follow journey a or c forms " short circuit ", all materials all can't be realized good Separation of Solid and Liquid.So general in the field of business of bag type filtering machine is used for Separation of Solid and Liquid less demanding field, is difficult to the Separation of Solid and Liquid operation of solid as major product.Under the prerequisite that does not solve " short circuit ", if obtain the solid product of high mother liquor clearance (perhaps high-purity) in filter bag, need to realize with clean solvent washing or by continuing dry method, increased supplies consumption and energy consumption.So, want to address the above problem, must solve compressed air " short circuit " problem in the binder process.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of high efficient solid and liquid separation bag type filtering machine, to solve compressed-air actuated " short circuit " phenomenon in pressure-filtering process.This filtering machine structure is simple, easy to operate, good effect of separating solid from liquid.
The technical solution of the utility model is on the basis of existing bag type filtering machine, design compressed air distributor, the compressed air distributor is made of compressed air access tube, source of the gas central distribution pipe and material gland, the compressed air access tube connects by removably with source of the gas central distribution pipe, source of the gas central distribution pipe passes material gland center and enters in material, source of the gas central distribution pipe lower end end-blocking is airtight, near the lower end, the compressed air distribution hole is arranged.
In pressure-filtering process, compressed air enters source of the gas central distribution pipe by the air access tube, be released in the center of material by the compressed air distribution hole, from the source of the gas center, compressed air is almost equal through stroke a, b, the c of material, each stroke material inside and outside pressure differential is close, the material of process almost complete simultaneously Separation of Solid and Liquid.
Source of the gas central distribution pipe can be designed to be able to extend to the different series length of filtering a basket middle part, bottom according to height of materials, and how many material glands can move up and down with inventory.
The utility model Separation of Solid and Liquid bag type filtering machine in use, at first according to inventory height in filter press, select the compressed air distributor pipe of different length, so that being centered close to material central authorities, compressed-air actuated source of the gas is advisable, material in the filter basket can be completed Separation of Solid and Liquid substantially simultaneously like this, thereby has stopped " short circuit " phenomenon in the appearance of top material; Then regulate the material gland, make its upper surface that compresses from top to bottom material, make in the situation that material is not full of the filter basket, compressed air is no longer from filter frame top " short circuit ".
The utility model is on the basis of the single bag type filtering machine of tradition, design a compressed air distributor, the source of the gas center is moved down, substantially stop compressed air in the situation that various inventory by " short circuit " phenomenon of top material and filter frame, realizes efficient Separation of Solid and Liquid.
